| # Description: |
| # This file defines a GNU autoconf M4-style macro for checking |
| # the presence and viability of both required and optional |
| # dependent packages, which may be internal or external to the |
| # current package. |
| # |
| # Five (5) macros are made available: |
| # |
| # * NL_WITH_REQUIRED_EXTERNAL_PACKAGE |
| # * NL_WITH_OPTIONAL_EXTERNAL_PACKAGE |
| # * NL_WITH_REQUIRED_INTERNAL_PACKAGE |
| # * NL_WITH_OPTIONAL_INTERNAL_PACKAGE |
| # * NL_WITH_PACKAGE |
| # |
| # Note, however, that NL_WITH_PACKAGE is deprecated and maps to |
| # NL_WITH_REQUIRED_INTERNAL_PACKAGE. |
| # |
| |
| # _NL_ARG_WITH_INCLUDES_OR_LIBS(PACKAGE-DISPOSITION, |
| # PACKAGE-SOURCE, |
| # PACKAGE-PRETTY-NAME, |
| # PACKAGE-VARIABLE-PREFIX, |
| # PACKAGE-SUCCINCT-NAME, |
| # PACKAGE-WITH-OPTION, |
| # PLURAL-WITH-OPTION-HELP-WORD, |
| # WITH-DIR-VARIABLE-MODIFIER) |
| # ---------------------------------------------------------------------------- |
| # This is a wrapper around AC_ARG_WITH that provides the ability to |
| # optionally specify a dependent package include and link library |
| # directories independently as |
| # --with-<PACKAGE-SUCCINCT-NAME>-<PACKAGE-WITH-OPTION>=<DIR>. |
| # |
| # If the package is specified as required, the use of |
| # --without-<PACKAGE-SUCCINCT-NAME> or the use of |
| # --with-<PACKAGE-SUCCINCT-NAME>=no will result in a fatal error. |
| # |
| # At the successful conclusion of the execution of the macro, |
| # two variables will be defined: |
| # |
| # * nl_with_<PACKAGE-SUCCINCT-NAME> |
| # * <PACKAGE-SUCCINT-NAME>_<WITH-DIR-VARIABLE-MODIFIER>_dir |
| # |
| # The package disposition and source are specified by: |
| # |
| # PACKAGE-DISPOSITION : This may be either 'required' if the dependent |
| # package is required or 'optional' if |
| # not. |
| # PACKAGE-SOURCE : This may be either 'internal' if the dependent |
| # package may be provided either |
| # internally or externally to the current |
| # package or 'external' if the dependent |
| # package may only be provided outside of |
| # the current package. This also serves as |
| # the default value for where the |
| # configuration script expects to find the |
| # package. |
| # |
| # The dependent package is specified in three forms: |
| # |
| # PACKAGE-PRETTY-NAME : The human-readable name by which the package |
| # will be referred for any diagnostic output. For |
| # example, "My Great Software Package". |
| # PACKAGE-VARIABLE-PREFIX : The package-specific prefix applied to variables |
| # defined as a result of running this macro for the |
| # packages. For example, "MGSP" here is transformed |
| # into MGSP_CPPFLAGS. |
| # PACKAGE-SUCCINCT-NAME : The package-specific name used for pkg-config, |
| # in temporary variables and on the |
| # configure command line. For example, |
| # "mgsp" here is used for --with-mgsp=DIR |
